Water worlds may be abundant in our galaxy
A new study suggests that our Milky Way galaxy is filled with planets like Earth, containing continents and oceans. If so, life might be common in the Mlilky Way. Source: https://earthsky.org/space/water-common-on-planets-pebble-accretion-milky-way…
People sleep less before a full moon
Researchers find that whether you live in a rural or urban environment, your sleep patterns are affected by the full moon. On the nights leading up to full moon, people fall asleep later and sleep less overall. Source: https://earthsky.org/human-world/people-sleep-less-before-full-moon…
Dark streaks on Mars may be caused by salts and melting ice
Researchers at the SETI Institute say that unusual dark streaks on sun-facing slopes on Mars, debated about for years, may be small landslides caused by a combination of salts and melting ice just below the surface.

Scientists Develop Transparent Wood That Is Stronger, Lighter Than Glass
Researchers at the University of Maryland have turned ordinary sheets of wood into transparent material that is nearly as clear as glass, but stronger and with better insulating properties. It could become an energy efficient building material in the future. CBC.ca reports: Wood is made of two basic ingredients: cellulose, which are tiny fibres, and lignin, which bonds those fibres together…
Metasurface enabled quantum edge detection
Metasurfaces provide unique platforms to realize exotic phenomena including negative refraction, achromatic focusing, and electromagnetic cloaking due to the engineered dielectric or metallic architectures. The intersection of metasurfaces and quantum optics can lead to significant opportunities that remain to be explored. In a new report now published on Science Advances, Junxiao Zhou, Shikai Liu and a research team in quantum information,…
Want to find life on Mars? Look deep underground
A new study from researchers at Rutgers University suggests that the best place to look for evidence of life on Mars is deep underground, where geothermal heat melted subsurface ice. Source: https://earthsky.org/space/mars-life-search-subsurface-ice-melted-by-geothermal-heat…
Researchers achieve quantum advantage
University of Copenhagen researchers have advanced their quantum technology to such a degree that classical computing technology can no longer keep up. They have developed a chip that, with financial backing, could be scaled up and used to build the quantum simulator of the future. Their results are now published in Science Advances. …
Weather on Jupiter and Saturn may be driven by different forces than on Earth
A trio of researchers, two with Harvard University, the other the University of Alberta, has found evidence that weather on Saturn and Jupiter may be driven by dramatically different forces than weather on Earth. In their paper published in the journal Science Advances, Rakesh Kumar Yadav, Moritz Heimpel and Jeremy Bloxham describe computer simulations showing that major weather systems on Jupiter…
Clovis made stone tools for only around 300 years
The Clovis, some of North America’s earliest inhabitants, only made stone tools during a brief 300-year period from 13,050 to 12,750 years ago, new research shows. Source: https://earthsky.org/human-world/clovis-stone-tools-300-years…
